Phys.org / Heavy water expands energy potential of carbon nanotube yarns
Researchers at The University of Texas at Dallas have developed a new electrolyte system that significantly boosts the energy-harvesting performance of twistrons, which are carbon nanotube yarns that generate electricity ...
Phys.org / 3D-printed rattlesnake reveals how the rattle is a warning signal
A team of researchers from The University of Texas at El Paso has uncovered new evidence explaining why the rattlesnake's rattle—one of nature's most iconic warning signals—has persisted and proven so effective across ...
Phys.org / Mangrove forests are short of breath, researchers warn
The tidal environment of mangrove forests serves as nurseries for many fish species. Researchers at the University of Gothenburg have measured carbon dioxide and oxygen levels in 23 of the world's mangrove areas. The study, ...
Medical Xpress / Experimental chemo drug triggers 'viral mimicry' signals that rally immune attack
In recent years, scientists have discovered that some chemotherapy drugs not only kill cancer cells directly, but at least in some patients, mysteriously also trigger their immune system to attack the cancer. That would seem ...
Medical Xpress / Active ingredient of Viagra can help treat rare genetic disease
Sildenafil—an active ingredient also marketed under the name of Viagra—improves symptoms in patients with Leigh syndrome. This has now been reported in the journal Cell by researchers at Charité—Universitätsmedizin ...
Phys.org / King penguins are the rare species benefiting from a warming world. But that could change
The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other—like flowers blooming too early and pollinating bees arriving too late. But researchers ...
Phys.org / Climate extremes hinder early development in young birds, research shows
New research from the University of Oxford shows that cold snaps and heavy rain can stunt growth and reduce survival prospects in UK great tit nestlings. However, breeding earlier within a season appears to buffer against ...
Phys.org / Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to ...
Phys.org / How volcanic eruptions and internal climate cycles jointly shape Asian monsoon rainfall
From the rice paddies of South Asia to the wheat fields of northern China, summer monsoon rains sustain the livelihoods of billions. Yet these vital rains fluctuate dramatically from decade to decade—a variability that ...
Phys.org / Friendly fungi hijack plant regulator to promote symbiosis
Plants are constantly on guard. Their roots are equipped with molecular alarm systems that detect invading microbes and trigger immune responses. Yet beneficial soil fungi routinely enter living root cells and establish close ...
Phys.org / Flying 2,000 km to find a mate—meet Australia's most determined seabirds
New genetic testing from the University of the Sunshine Coast has uncovered the extraordinary lengths a group of Queensland seabirds will travel to keep love blossoming on their little island. It's a common complaint for ...
Phys.org / Bromacker deposit is 4 million years older than previously thought, new dating reveals
Analysis of a volcanic ash tuff layer, only a few millimeters thick and discovered during excavations in 2024, revealed that the fossil-bearing Bromacker rocks are 294 million years old—four million years older than previously ...
